Insects are persistent little buggers. They can find their way into your home in many ways, one of which is through your HVAC system. You may not think to call an HVAC technician if you notice an more insects in your home. If insects seem to be around ducts and vents that carry air through your home, call and HVAC professional. Here's the connection between insects and your HVAC system. What can you do to keep these unwelcome guests out of your home?

How Insects Get into HVAC Systems

The top entry point for insects via an HVAC system is air vents. If you see spiders and other insects around your vents, this could be the source of your insect problem. One way to deal with this issue is to have insect netting or screens installed over your HVAC vents. You can have this done by and HVAC professional, or you can do it yourself by:

• Removing HVAC vent covers
• Measuring each HVAC vent
• Cutting the screen/netting so it fits the HVAC vent opening

If you install insect netting or screening on exterior HVAC vents, use caulking. This forms a tighter seal around the HVAC vent before replacing the cover.

Check for Other Cracks and Insect Entry Points

As long as you're busy caulking outside your home, look for other potential entry points. Along with HVAC vents, insects can get into your home through other means. Cracks in walls or foundations, around dryer vents, or around windows and doors are the main areas. Those that aren't sealed or weather-stripped can cause a way in for insects.

Be Mindful of Plants around Exterior AC Units

Insects can also clog the exterior part of your HVAC unit if it's surrounded by weeds or flowers. If this is the case in your yard, clear the area immediately around your outside HVAC unit. Doing so will deter insects from getting into the unit and clogging it.

Check around Your Window Units

If you don't have a full HVAC system, you may use a furnace and have window units. If this is how you cool and heat your home, be aware that insects can get in through the "fins" on either side of a window AC unit. Keep insects outside where they belong by:

• Adding screen material over the fins or panels to keep insects out
• Contacting our HVAC professionals to make sure your window units installation is correct
• Using foam strips to create an extra barrier against insects

What Not to Do

The one thing you don't want to do about insects coming in via your HVAC system is use pesticides. First of all, this isn't very effective. Second, doing so can spread harmful chemicals throughout your indoor air.
